煤化工包括煤的加工、煤的气化、煤的液化等,在煤气化、煤液化、煤制油及煤基醇醚燃料的工艺过程中,需要大量的氧气,我国“煤代油”战略及相应能源政策的实施,为大型空分设备在煤化工领域的应用带来了机遇。从20世纪90年代初期开始,中国空分设备公司就开始了对煤化工领域空分设 Coal chemical industry, including coal processing, coal gasification, coal liquefaction, etc., in the process of coal gasification, coal liquefaction, coal oil and coal-based alcohol ether fuel, requires a lot of oxygen, China’s “coal instead of oil” strategy And the implementation of the corresponding energy policy, has brought opportunities for the application of large-scale air separation plant in the field of coal chemical industry. Since the early 1990s, China’s air separation equipment company has started the field of coal chemical separation
